Yes, it may be tacticool to have a 100 or 200 round drum magazine. But it’s interesting to note that the mechanism (thankfully) failed the assailant. This from what I have seen is not an uncommon occurrence. Many of these overly extended magazines push the envelope on reliability a bit too far for my consideration.

I am no expert, but if I were to rely on a magazine for my life’s well being, I would probably stick to a 20 or 30 round magazine of high quality. This also may explain the reports of people running past the assailant to escape.
